Provided here is a method for providing a coating on a plurality of substrate particles utilizing concurrent dissolution and deposition processes occurring among a plurality of source particles. Both the plurality of source particles and the plurality of substrate particles are freely immersed in the aqueous solution to form a slurry. A pH of the aqueous solution the electrochemical potential between the plurality of source particles and the aqueous solution establishes the source particles at a corrosion potential providing the concurrent dissolution and re-deposition of a cationic species on the source particles. Agitation of the slurry generates close proximity and/or brief contact between source and substrate particles causing substrate particles pass through the local environment of the source particles, resulting in some portion of the cationic species depositing at nucleation sites on the substrate particles.

A powder consolidation method and apparatus make use of corrosion processes occurring on surfaces of metal particles to consolidate a metal-containing powder into a formed body. The method includes contacting metal particles with an acidic or basic liquid at a pH and potential at which dessolution of metal from the particles and reduction of soluble metal-containing ions to metal on surfaces of the particles can co-occur, such that the metal powder agglomerates to form a body.

The development of new material synthesis and manufacturing technologies may be one of the most important areas of research in the 21st century. In this study, we introduce the concept of a novel additive manufacturing technology, referred to as electrochemically‐driven powder consolidation (EDPC), which utilizes naturally occurring electrochemical potentials to consolidate metal and non‐metal powders to rigid bodies and complex shapes. In contrast to existing manufacturing techniques, the proposed technology does not require additional energy input in the form of pressure, heat, and/or laser power, opening new pathways for the development of a more energy‐efficient, low‐cost additive manufacturing technology. Using the example of lead, we outline the concept of EDPC and propose a five‐stage model that describes the physical and chemical processes that govern the observed consolidation. A series of consolidation experiments with other elements (e.g. Sn, Zn, Cu) was conducted to identify the rate‐controlling mechanisms and determine crucial process parameters of a potential EDPC manufacturing technology. Finally, the EDPC process was found to also hold great promise for the bulk synthesis of a variety of new materials, including nanoparticles, pellets, metal foams, and advanced composites.
